Method for upmixing a downmix signal having a first channel and a second channel into an upmix signal, having the steps of: carrying out a correlation comparison in order to determine correlated signal components of the first and second channels of the downmix signal, wherein a first channel of the upmix signal is determined on the basis of the first channel of the downmix signal, a second channel of the upmix signal is determined on the basis of the second channel of the downmix signal and a third channel of the upmix signal is determined on the basis of the correlated signal components; determining at least one fourth channel of the upmix signal by inversely coding the first, second or third channel of the upmix signal. |
